Cannot Block p2p Torrent using NBAR in IOS ver 15 Adv IP Services

Paul Kazzi

Wondering if anyone has any solutions to this issue. Have tried blocking BitTorrent and even Skype to no avail. The actual rate and drops show up in "show policy-map interface" but these apps still can get out to Internet. Cannot seem to block this traffic...

ip cef

class-map match-any p2p
match protocol bittorrent
match protocol gnutella
match protocol fasttrack
match protocol kazaa2
match protocol winmx
match protocol edonkey
match protocol irc
match protocol skype

policy-map InboundFromLAN
class p2p
   drop

Hi,

I cannot gurantee this will help, but if it's not too much trouble, why not try upgrading IOS to

c880data-universalk9-mz.152-1.T.bin

Any x.0 release will be improved upon soon thereafter in subsequent releases. I avoid x.0 releases or try to move away from them as soon as possible.

If you need an attribution to justify the upgrade effort, try reading the 15.2/15.1 release notes for fixed issues related to your problem.
